To all whom it may concern.-

Be it known that I, GABRIEL PATUREAU', a citizen of France, residing at 14 Rue Danton, Levallois-Perret, Seine, France, have invented new and useful Machinery for Pasting Strips of Paper on Pasteboard Boxes and other Hollow Objects, (for whichI have obtained a patent in France, No. 202,825, bearing date December 27, 1889,) of which the following is a specification.

-My invention relates to new machinery for efiecting automatically the pasting or cementing of strips or bands of paper or other material round pasteboard boxes and such like hollow objects, which operation has hitherto mainly been done by hand.

rious stages of the covering operation. Figs. 27 and 28 show the sliding connection of rod 91 91*, and Fig. 29 is a detail side elevation of the ratchet-wheel and spring pawl hereinafter explained.

This machine is designed to carry out the following operations: First, preparation and pasting of the paper strip or strips to be applied to the boxes; second, forward feed of the paper strip; third, cutting the strip in lengths corresponding to the size of the boxes; fourth, feed of the boxes on to the mandrel where the paper strip is to be applied; fifth, coiling pasted paper strip on to the box and pressing the one edge of the paper on to the bottom of the box by a revolving brush; sixth, expelling the boxes after pasting, and seventh, turning the other edge of the paper strip over the edge of the box, and pasting the same on to the interior thereof.

This machine may be employed for covering boxes with a single paper strip. In the arrangement shown, however, there are two paper strips 1 and 2 pasted on to each other, of which the latter is narrower than the former and serves for ornamentation, as shown at Figs. 3 and 23, the strip 2 being in the first instance pasted on to 1 in such a position that when the combined strips are coiled on to a box, the lower edge of 2 will be flush with the bottom of the box, so that the part of 1 beyond such edge can be turned over on to the bottom of the box as at Fig. 24., and the other edge of 2 will extend partly up the width of the box as at Fig. 26, the remaining part of 1 being subsequently covered by the lid of the box. The said paper bands 1 and 2 are coiled on reels 3, 4 carried by brackets on the framing, and are led thence over guide rollers 5, 6 to disks 7, 8 which are partly immersed in paste troughs 9 and 10, so that the bands in passing over them cause them to revolve and thereby to carry the paste on to the side of the strip which is in contact with the disk. From the disk 8 the paper strip 2 is led over roller 11 up to roller 12 over which strip 1 is also led, the latter being made to present its pasted side outward so that as 2 passes in contact with it, also with its pasted side outward, the two strips become cemented together forming a combined strip 13 which passes over roller 14. into the machine with its to cover abox.

pasted side upward. From the roller 14 the paper strip passes between apair of feed rollers 15 of which the lower one receives an intermittent step by step rotary motion in the direction of the arrow by toothed gear 16, 17. The wheel 16 is fixed on a shaft 18 on which is fixed the part 19 of africtional ratchet device of well known construction,shown in elevation withthefrontplate removedatFig. 5,theother part 20 of which is loose on the shaft 18 and has an arm 21 connected by a rod 22 toa double ended lever 23, the lower end of which is connected, by a rod 24 to a rocking arm 25 (Fig. 2). This arm is pivoted at bottom to the framing and carries at its upper end a roller 26, Fig. 18, which is caused by a spring 29 acting on arm 25 to bear against the periphery of a cam 27 fixed on the driving shaft 52 of the machine.

The cam 27 is so formed as at each revolution of the shaft 52 to move the arm 25 outward, thereby causing the part 20 of the ratchet device to be turned through a certain angle in the direction of the arrow Fig. 5 and as in such motion 20 is made to carry the part 19 with it, by the well known wedging action of the rollers on the cam surfaces of 19, shaft 18, and wheel 16 are also turned in the same direction, causing wheel 17 and rollers 15 to revolve to a correspondingly greater extent so as to draw forward a length of the paper band 13 corresponding to the length required On the projection of the cam 27 receding from arm 25, this is drawn back by its spring 29 causing part 20 of the ratchet to be turned back to its oiiginal position, while leaving 19 and 18 stationary as the rollers then release their grip on the cam surfaces.

An endless band 30 passes around the lower roller 15 and round a smaller roller 31, on which bears a small roller 32, so that the paper band travels along on the band 30 between these rollers and passes thence on to a narrow table 33, and between this and another roller 34. The table 33 extends forward some distance as shown at Figs. 1, 2 and 4, and its front end has a long slot as shown at Fig. 4. It terminates just behind a pair of shears 35. In front of it is a narrower table 36 carried by a carriage 37 having ato and fro motion imparted to it from the table 33 to the revolving mandrel as will be presently explained, the table 36 being of a width to pass into the slot of table 33 as it is carried backward by the carriage. The latter consists of a bracket on which is mounted a roller 38 above which is a second roller 39 mounted on an arm 40 pivoted to the carriage and pressed downward so as to cause 39 to press upon 38 by an adjustable spring 41 carried by the carriage. To the side of the roller 39 is fixed a ratchet wheel 42 with whichgears a spring pawl 43 carried by the arm 40, the ratchet and pawl being formed so as to offer a certain resistance to rotation of the roller 39 in the backward direction, but to allow of free rotation in the direction of the arrow, Fig. 2, when the cut strip is being drawn from between the rollers by the revolving mandrel. On each side of the arm 40 is a downward extension 44 with rollers 44 at their lower ends.

The carriage 37 has pivoted to it a second arm 46 carrying at its end a pressing roller 47; this arm is supported upon an abutment 48 on the carriage, and when the latter is brought into the position shown at Fig. 2, with the roller 47 immediately underneath the mandrel 45, the roller 47 is pressed upward by a rod 49 acting on the end of the arm 46 so as to press the end of the paper band on the carriage against the box situated on the mandrel. As the carriage 37 travels back from the mandrel 45, the inclined rods 50",

inclines 50 on the ends of levers 51 actuated feed rollers 31, 32, on to table 33, passes 1111- der a roller 34 and along table 33 toward the carriage 37, and the feed of the band is so timed as to commence as the carriage is about completing its backward travel, so that by the time such travel is completed the paper band will have passed between the rollers 38, 39 and up to the vertical center line of roller 47 on which the end then rests. At this moment the inclines 50 of levers 51 are made to descend so as to release the extensions 44 of arm.

40 and thus allow the roller 39 to be pressed down by spring 43 and thus cause it to nip the paper and hold it firmly in the position described. The carriage then begins to travel forward again while the feed of the paper band continues, the rollers 38 39 being made to draw the end forward at the same speed as the feed, and this continues until the carriage again arrives at the forward position shown at Fig. 1, when the end of the paper strip resting on roller 47 will have been brought between this and the mandrel 45. The roller 47 is then pressed up as described by rod 49 acted upon by cam 49 so as to press the pasted side of the paper band against the box on the mandrel. By the time the carriage arrives at the end of its forward motion the shears 35 will have been made to advance in the opened position shown at Fig. 6, so as to pass with its two limbs above and below the paper band, just in front of the end of the table 33, and in being then closed, will out the paper band through, thereby severing a length 011 the carriage exactly equal that required for covering a box, and this length will now be wound upon the box by the rotation of the mandrel.

The several movements of the above described parts are elfected as follows: On the driving shaft 52 of the machine is a cam groove 53 with which engages a roller 54 on a rod 55, passing between guide rollers 56 and having its end pivoted to'a crank pin 57 on a plate 58 which is loose upon a shaft 59 (Figs.

14 and but is adjustably connected to a second plate 60 fixed on the shaft by a slot and 'screwbolt 61. On the shaft 59 is also fixed a lever arm 62 connected by a link 63- to a lever 64 pivoted at 65, and having at its.

which gears a roller on a double ended lever 71 pivoted to a pin on the framing and having at its other end a roller engaging with a groove 72 on'the under side of a sliding can.

riage 73 sliding between guides on the framing.

fixed to a spindle 74 passing loosely through the boss of the carriage 73 and acted upon by a helical spring 75 which tends to keep the blade in the raised or open position shown. On the end of the spindle 74 is fixed a finger 75, opposite which is an arm 76 on a spindle 77 carried in bearings on the framing, and having at its front end an arm 78 which is acted upon periodically by a face cam 79 on the shaft 52. Thus it will be seen that at each rotation of shaft 52, the carriage 73 will be first moved forward so as to bring the shears into the position with the paper band between its blades, asdescribed, after which, by means of cam 79 the arm 76 will be made to turn so as to press against finger 75 and thus close the shears and cut the paper band, and lastly, the carriage with the shears will be moved back again by the cam 70. It is necessary that just before the cutting off of roller 84, which by its weight and the weight of the arm 82 presses on the paper band and prevents the latter from springingback after it has been cut.

carriage 37 is in the forward position at Fig. 2, enables the lever to be free of a roller at the top of the carriage, so that its preponderating rear end can bear with roller 84 on the paper as described. When the carriage 37 begins to travel backward, the roller 85 in bearing against the elbow of the lever 82, depresses its front end and thereby lifts the To this carriage is fixed the lower blade of the shears 35, while the upper blade is The other'end of the arm 82 is formed with a bend, which, when the roller 84 oi the paper band so that this can be fed forward'again.

I will now proceed-to describethe-construction'and operation of the mandrel 45, and of the devices for feeding the boxes to be covered on to the same. The mandrel and parts operating the same are shown at Figs. 2, 4 and 6.

The mandrel head 45 is fixed on acylindrical body 86 rotatable in'a fixed bearing 87 and carrying at its back end a toothed pinion 88 by which it receives rotary motion from the shaft 52 through the spur wheel 89. The

mandrel head is split longitudinally as shown at Fig. 4 so as to be formed into a number of spring segments and it has a central coned opening, into which fits aconed disk 90 having a stem 91 passing through 86 and having 'at its rear end a screwed collar 92 against which bears a spring 93 which tends to press the stem and disk backward. When in this backward position, the disk 90 slightly expands the spring segments of the head 45. At therear end of the mandrel is a double ended lever 94 the lower end of which is acted upon by a cam 95 on the shaft 52 while the upper end has an adjustable pin 96 which 'bears against the end of the stem 91, so that at certain intervals of time the lever 94 is caused by a small swell or cam 95 to first push the stem and disk slightly outward without protruding the latter beyond the mandrel, s0

that this can contact in order to allow of the ready placing thereon of a box, after which the lever recedes so as to allow the disk 90 to 'be pushed backward to expand the mandrel paper strip coiled upon it, and lastly the lever is made to move the stem and disk considerably forward by a large swell on the cam shown at Fig. 6 so as to push the box off the mandrel after which the disk is brought back by the spring 93 again.

In order to assist in the throwing off of the box in case it should stick on the mandrel and also to cause it to fall bottom downward on to achute the device shown at Fig. 6 is employed. At the top of the bracket 87 is carried by means of links a bar 111 having a beak at its front end, which when the bar is pushed forward on its link connections, comes in contact with the edge of the box on the mandrel and pushes it off the latter thereby also causing the box to turn partly round in falling. The said motion is imparted to bar 111 by the upper extension of lever 94,

'to which is pivoted a rod 112, having a pawl '115 rapidly draws 111 back again.

Assuming a box to have been placed upon the rotating mandrel head 45 as described,

and that the carriage 37 has at the same time moved forward so as to bring the roller 47 with the end of the pasted paper strip lying upon it, immediately beneath the mandrel head, then on the roller 47 being pressed upward by the rod 49 acted on by cam 49 it will press the pasted side of paper strip against the box on the mandrel, and consequently as the latter revolves, the paper strip will be wound upon it. While this is being effected, a revolving brush 97, Figs. 2, 4 and 17 carried by an arm 98 and driven by cords 99, 100 and pulleys 101, 102, 103 and 105 from a pulley 104 on the mandrel body 86, is brought up against the paper band as this is wound on the box so as to cause its projecting edge Fig. 23 to be turned over on to the bottom of the box and pasted thereto as at Fig. 24 for which purpose the brush arm 98 is carried by a spindle 106 having at its lower end a toothed pinion 106 gearing with a toothed sector 107 pivoted to a fixed bracket on the framing, and having an arm 108 bearing with a roller against a face cam 109, which in connection with the spring 108 at the required movement turns the sector 107 and pinion 106 so as first to bring the brush 97 in contact with the edge of the box while the paper strip is being wound thereon, and then to move it away again, so as to allow the box to be pushed off the mandrel as described.

For placing the boxes to be covered with paper upon the mandrel 45, the following mechanism is employed: A sliding carriage 116 Figs. 6 and 11 receives ato and fro movement from the cam drum 117 on the shaft 52 by an arm 118 carrying a roller engaging with the cam groove. The carriage carries upon a cylindrical projection 116 a rotatable cylinder 119 having a cam groove 120 into which takes a roller 121 carried by a fixed frame 122 so that by the to and fro motion of the carriage 116 the cylinder is caused by cam groove 120 and roller 121 to turn to and fro through a certain angle. To the front of the carriage 116 is fixed a plate 123 in slots in which slide two horizontal curved j aws 124, and above thesejaws the plate carriesachute 125 into the upper end of which are placed by hand the pasteboard boxes to be covered. The jaws carry at the back of the plate rollers 126 situated in the eccentric slots of cars 127, carried by the cylinder 119. The result of this arrangement will be that as the carriage recodes from the mandrel 45, the partial rotation of 119 and 127 causes the jaws 124 to move apart, thereby allowing one of the boxes to drop between them from 125 on toa guard plate 128 at the extreme end of such backward motion, whereupon the carriage will be immediately moved forward again, causing the jaws to advance and hold the box between them. To the one jaw 124 is fixed a shield 129 which when the jaws are moved apart as at Fig. 11 projects partly in front of the space under the chute 125, and thus prevents the box resting on plate 128 from falling forward. 130 is a plate secured to the plate 123 in front of the jaws and having a circular hole for the box to pass through. Centrally between the jaws at the back of the box held thereby is a disk 131 fixed on a stem 132 passing back through the cylinder of carriage 116 and having its end fixed to another carriage 133 which receives a to and fro movement from the cam drum 134 on shaft 52. This motion is so proportioned to that of carriage 116, that as this advances toward the mandril 45, the disk 131 is made to advance at the same speed, but when 116 has arrived at the end of its travel, just in front of the mandrel, the disk 131 continues to be moved forward so as to push the box from between the jaws 124 and on to the mandrel head, the box having its open end presented toward the latter. On the carriage 116 now receding again, the carriage 133 is held stationary for a certain time, thereby causing the disk 131 to hold the box against the mandrel during the time the paper strip is being coiled upon the former. The carriage 133 then recedes again bringing the disk 131 into its original position between the jaws before these have opened out sufficiently for a fresh box to drop between them.

The paper band 13 is of such a width, that, when secured on the box as described a portion thereof projects beyond the edge of the box, as at Fig. 24 for the purpose of being turned over such edge as at Fig. 25 and pasted against the inner surface as shown at Fig. 26. For effectingthis operation, the box falls from the mandrel 45 along a chute 135 on to a revolving circular table 136. This table shown more particularly at Figs. 1, 7, 8, 9 and 10 is mounted on a fixed spindle 137 and receives a step by step rotary motion from a cam 138' On the under side of table 136 is formed a 1 ratchet ring 147 having as many teeth as the .ratchet wheel l46-aud resting upon a corresponding ratchet ring 148 fixed to the framing 149'. Thus at each movement of the table 136,147 shifts round one tooth on 148 (the table being capable of rising slightly for this purpose) and falls into the next tooth, thus insuring the exact required movement every time for bringing a box beneath the operating pistonl50.

At the circumference of the table 136 are cir-v cular holes 151 corresponding in number to the teeth of the ratchet wheel 146 and of such size that the boxes descending from the mandrel 45 through chute 135 can drop freely therein so as to rest with their bottoms upon an annular rail 152 fixed on the framing. Thus as the table travels round by a step-by-step motion, it car ries the boxes round with it, until they arriveover a disk 153 situated in a gap of the rail 152, at the same level as the latter; this disk is faced with caoutchouc and is connected to a tubular stem 154. The lever end of this stem is fixed to a recessed disk 155 connected by an elastic diaphragm to a second disk 156 on a stem 157 which is supported and actuated by a lever 158 pivoted to the framing and having first a roller 158 situate between collars on the stem 157 and secondly a roller 159 bearing on the periphery of a cam 160 on the shaft 139 shown detached at Fig. 7 which cam is so formed that at each rotation it causes the lever to drop a certain distance by its Weight, and then to rise again so that at each rotation of the shaft 139 the lever 158 is made to move the stem 157 rapidly downward to acertain extent immediatelyafter one of the boxes has been brought upon the disk 153, thereby creating a slight vacuum below the box, which causes this to adhere to the rubber faced disk 153. On the tubular stem 154 of the latter is a coned friction disk 161 gearing periodically with a segmental friction wheel 162 on shaft 139, so that the stem 154, disk 153 and the box upon the latter receive a rotary motion by this means during part of a revolution of shaft 139. Above the disk 153 is a slide 163 carried in a guide 164 on a-bracket 164 fixed to the framing, and within the slide is a sliding stem 165 terminating at its lower end in a piston 150. The slide 163 has two lateral studs 163 projecting through slots in the guide 164 as shown at Fig. 8, and connected to elbow levers 166, pivoted to bracket 164 and actuated by a cam 167 on shaft 139, so that at each revolution of the latter the slide receives an up and down'movement between which it has a dowel, when in the loweredposition. To the stem 165 is connected an elbow lever 168 also pivoted to bracket 164 and actuated by a cam 169 on shaft 139 so as to impart an up and down motion to piston 150. Passing diametrically across the table 136 is a rod 170 the one end of which is connected to a slide 171, having an arm 172 passing through a slot in the frame, and engaging with a cam 173 on shaft 139, by which means the slide and rod receive a to and fro motion at each revolution of the shaft. The rod 170 is guided in such motion by sliding through a hole in the projecting end of the spindle 137 of the table. The other end of the rod 170 is formed with a curved beak, as shown. The operation of these parts is as follows: A box having been brought upon the disk 153 and put into rotation thereby as described, the rod 17 O is made to advance and, by'means of its beak, to bend the projecting edge of thepaper inward over the edge of the box as at Fig. 25, after which the rod retires again. The slide 163 and piston 150 are then made simultaneously to deboxes.

scend so as tobring the bottom surface of the slide upon the edge of the box, while the piston passes into the box, thereby bending the edge of the paper strip downward into the box and causing it to adhere with its adhesiveside against the inner surface of the latter. The piston is for this purpose covered by a diaphragm 174 of caoutchouc stretched over the under side of the piston and attached to the edge of the slides under face, so that as the piston is made to descend into the box it will stretch the diaphragm to a corresponding extent and press it against the inner surface of the box. This having been accom plished, the piston is moved upward out of the box by its lever and cam, while the slide 163 is momentarily held upon the edge of the box by its lever and cam, in order to prevent the box from moving up with the piston, and when the latter is clear of the box, the slide also rises. The disk 156 will meanwhile have been moved upward by the lever 158, before the piston 150 descends into the box so that this is no longer held by suction on the disk 153, and will have remained stationary while piston 150 descended upon the table 136, now being moved round one step again. The finished box as at Fig. 26 is carried away from the disk and eventually falls down out of the hole 151 as it is carried beyond the edge of the framing, as seen at Fig. 10 while atthe same time afresh box is brought upon the disk 153, and the above described operation is repeated.

Although I have described the machine as operating upon cylindrical boxes, yet it may also be adapted to operate upon boxes of other shapes. Thus Figs. 20 and 21 showto an enlarged scale respectively a longitudinal section and end view of a modified construction of the mandrel 45, suited for operating on oval In this case it is necessary that the mandrel in rotating shall always present its lowest edge in one and the same plane, so as to always remain in contact with the pressing roller 47, and also, that it shall remain stationary in a certain position .When the box is being placed upon by the disk 131. For these purposes the mandrel is constructed and operated as follows: The mandrel head 45 which is of oval shape, is not fixed to the body 86 but is capable of sliding transversely upon the front face thereof, by means of a plate 45 formed in one therewith sliding between dovetail guides 86 formed on 86. The plate 45 is connected bya pin 175 'to a ring 176 WlllOll can slide round upon a ring 177 fixed in an adjustable manner by screws 178 to slotted lugs 179 on the bracket 180 of the mandrel. From this arrangement it will be seen that if the ring 17 7 be fixed more or less eccentrically to the axis of the mandrel, this, in revolving and thereby causing plate 45 to draw ring 176 round on ring 177 will effect alateral shifting of the plate 45 and mandrel head 45 between the guides to an extent corresponding to the eccentricity of ring 177, and this-eccentricity is capable of being so adjusted relatively to the proportions of the major and minor axes of the mandrel head, that the part of the latter which for the time being is lowermost will always be situated in one and the same horizontal plane, as indicated by the dotted lines. For facilitating the rotation of the ring 176 on 177, the former is provided with small rollers 181 running upon the latter. The mandrel head 45 is split and is expanded by a coned disk actuated at the proper time by rods 91, 91 and lever 94 in the same manner as described with the circular mandrel. As however in the present case the front part 91 of the rod 91 has to partake of the lateral shifting motion of the mandrel head, it is connected to the part 91 by a sliding connection shown in longitudinal and cross sections at Figs. 27 and 28, namely a grooved head 183 is fixed on 91 in which slides a block 184 carried by 91. For effecting the temporary stoppage of the mandrels rotation when the box requires to be placed thereon, the mandrel body 86 is connected to its pinion 182 by means of a conical friction clutch, of which the part 185 is formed in one with the pinion 182, while the part 186 is attached to arms 187 projecting from the rod 91 of the coned disk 90. A spring 188 in the bracket 180 tends always to press the part 186 in gear with the part 185 in which case the mandrel 45 will be carried round by the pinion 182, but when the lever 94 acted upon by the cam Fig. 6 as before described presses the rod 91 inward so as to relieve the mandrel head of the pressure of the coned disk 90, preparatory to receiving a box, the part 186 of the clutch will at the same time be drawn back out of gear with 185 and consequently the mandrel will remain stationary until on the backward motion of lever 94 the spindle 91 is pressed back by its spring 188 and thereby puts clutch 186 in gear with 185 again.

To insure the exact proper position of the mandrel head 45 when it is brought to a standstill for receiving a box, the clutch 186 has a notch 189 into which enters a spring stud 190 carried by the bracket 180,when 186 is pressed forward by the lever, the notch being splayed laterally so as to cause it to engage with the pin and automatically adjust the position should the clutch be shifted slightly to one side or the other on being disengaged.

Having thus described my invention, what I claim is- 1. In a machine for covering boxes, a revolving expanding mandrel for receiving the boxes to be covered, consisting of a split mandrel head 45 on a cylindrical body 86 having a toothed pinion 88, by which it is rotated from a shaft 52, aconed disk 90 fitting a coned seat in the split head 45 and connected to a stem 91 acted upon by a spring 93 so as to be retracted and thereby to expand the mandrel head, and a lever 94 acted upon by a cam 95 on shaft 52 so as at fixed intervals to push forward stem 91 and disk 90 thereby allowing mandrel head 45 to contract and at the same time pushing off the box therefrom, substantially as described.

2. In a machine for covering boxes, the combination of a revolving expanding mandrel 45 with an appliance for placing the boxes on the mandrel consisting of a sliding carriage 116, curved jaws 124 for holding the boxes, chute 125 for delivering boxes between the jaws, rotary cam cylinder 1 l9 for moving jaws 124 to and from each other, and disk 131 between the jaws advanced by carriage 133 for pushing the boxes from between the jaws on to the mandrel, substantially as described.

3. In a machine for covering boxes, the combination of a revolving mandrel 45 with a reciprocating carriage 37, with table 36, pressing roller 47, fixed nipping roller 38, and movable nipping roller 39 carried by pivoted arms 40,40 acted upon by bar 50",substantially as and for the purpose set forth.

4. In a machine for covering boxes, the combination with a reciprocating carriage 37 having a fixed roller 38 and movable roller 39, carried by arms 40, 40, of a bar 50 acted upon by levers 50 and a toothed segment arm 64, 66 actuated by cam 53 and crank-arm 57 and gearing with a toothed rack 67 on the under side of the carriage 37, substantially as described.

5. In a machine for coveringboxes, the combination of a revolving mandrel 45, areciproeating carriage 37, appliances for intermittently feeding forward a pasted paper strip on to the reciprocating carriage, a cutting device 35 for cutting ofi a length of paper strip after it has been brought by the carriage 37 to the mandrel 45, and a pressing lever 82 with roller 84 which is made to bear upon the paper strip at a point behind the cut at the moment when the cut is being effected, substantially as described.

6. Ina machine for coveringboxes, the combination with the appliances whereby a paper strip is pasted around the boxes of a revolving table 136 having recesses 151 for the reception of the covered boxes, a circular rail 152 on which the boxes slide, a revolving disk 153 upon which the boxes are consecutively brought by the table, a rod 170 for turning over the projecting edge of the paper strip of the box situated on the disk 153 and a vertical slide 133 with stem and piston which is caused to descend into the box so as to turn down into the same the turned over edge of the paper strip, substantially as described.

7. In a machine for pasting or cementing a paper or other strip on to a box or other hollow object, the combination of a. pasting wheel for applying paste to one side of a paper strip as it is drawn from the roll, a pair of feeding rollers having a step-by-step motion for feeding forward a length of paper strip required for pasting on a box, a shearing device for shearing olf such length as it is fed forward, a sliding carriage for conveying the paper strip to the box intended to receive it, a revolving mandrel on to which the boxes are consecutively conveyed bya pair of jaws and a sliding disk on a reciprocating carriage, a pressing roller for pressing the paper strip on to the box placed on the mandrel, a revolving brush for causing the paper strip to adhere to the box, a central disk in the mandrel which is protruded when the paper strip is pasted on to the'box so as to force the box off the mandrel, a revolving-table for receiving the boxes after the paper strip has been pasted thereon and conveying them to a revolving disk, an arm extending across the table for bending the edge of the paper strip over the 15 edge of the box, and a vertically reciprocating pistonfor forcing the said edge of the paper strip down into the interior of the box so as to adhere thereto, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 22d day of January, A. D. 1891.
